Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed May 13, 1910. Serial No. 561,063.

To alt whom it may concern:

Be it known that I, JACOB \VmN'rz, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented a new and useful Improvement in Furnaces, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to furnaces, and has particular relation to furnaces designed to use hydro-carbon oils or other liquids as fuel. In furnaces of this type, it is necessary to atomize the oil fuel in order that it may be thoroughly mixed with the air supply, and it has been found that steam is one of the best agents for atomizing the oil. A serious disadvantage in the use of steam for this purpose, however, is found in the fact that it is wet and the water carried by it is thrown into the fuel supply.

My invention has for one of its objects the obviation of this disadvantage.

To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the following claim.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :Figure l is a front elevation of a furnace equipped with my device; Fig. 2 is a side elevation thereof; Fig. 3 is a vertical section of the furnace proper on the line 33 in Fig. 2; Fig. 4 is a cross section of the furnace on the line G tl in Fig. 2.

In the drawings I have shown my improved device in connection with a heating furnace which comprises a rectangular box A provided with suitable supports A. The box A will usually be formed of metal, and is lined with walls and floor of fire brick a and is rovided at one side with the usual door. l/ ithin the walls is the heating oven B through which extends a supplementary floor b on the under side of which is a transverse baille b. The space between the supplementary floor and the floor proper forms a combustion chamber C from which lateral fiues a lead into the heating oven B. A burner D is directed through the front wall of the furnace proper into the combustion chamber C. A chamber H opens directly from rear end of the burner. A fuel supply pipe E is connected with chamber H, and it will be understood that the fuel supply ma be any hydro-carbon oil or like fuel. 'n order to permit combustion of this fuel, it is necessary that it first be atomized, and although any pressure fluid may be used to atomize the oil, steam is found to be the most satisfactory agent for this purpose. I accordingly provide a steam supply pipe G, the main line 9 of which extends exteriorly of the furnace to the front wall thereof extends thence through the fire brick walls of the furnace 0n the sides and at the back of the heating oven B, and is finally connected with chamber H. The portion of this pipe which extends through the furnace walls is embedded securely in the walls as is clearly shown by Figs. 3 and 4. A pipe section 9 leads from the main line g before the latter passes into the furnace wall, and the sections 9 are connected with a steam trap g from which leads a discharge pipe 9 A pressure regulating valve 9 is also provided in the main line before it passes into the furnace wall, and a suitable indicator shows when the steam is varying from the required pres sure. Drip cocks g may be provided at suitable points in the steam line for the purpose of further draining the pipes of water. An air supply pipe F is also connected with the chamber fl.

The operation of a furnace so equipped with my improved device is obvious. The steam is admitted into the main line, and is at once drained of most of the water it is carrying by the steam trap connected with the main pipe line. The steam line then passes through the walls of the'furnace surrounding the heating oven on three sides, so that when the steam finally emerges from this portion of the pipe, it is for all practical purposes thoroughly dry steam. When the steam is then admitted to the atomizer with the hydro-carbon oil, it is both thoroughly dry and at a temperature such as to promote combustion and secure the full heating effect of the fuel. The resulting vaporized fuel burns with intense heat and renders a furnace equipped With such device one capable of extremely eflicient and economical operation. The absolute dryness of the steam has a further important advantage in that the tendency that Wet steam might have to cause the material being heated to scale is avoided.

Other modes of applying the principle 01 my invention may be employed instead of the one explained, change being made as re gards the mechanism herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed. 7

I therefore particularly point out and distinctly claim as my invention The combination of a furnace comprising a heatingchamber inclosed by walls of refractory material; of a burner, an air-supply pipe connecting thereWith; a fuel-supply pipe; and a pipe extending horizontally from said front Wall through one side Wall, the rear Wall, and the other side wall, and being connected at one end with said burner and at the other end with a steam-supply pipe; said horizontally extending pipe being contained Within and in contact With the Walls of said chamber thereby permitting the direct conduction of heat from said heating chamber to said pipe.

Signed by me this 11th day of May, 1910.
